developed by NikolaiT. It is used to identify or "score" the operating system (OS) of a remote host by analyzing how its TCP/IP stack is configured during a connection. github.com 🛠️ What is Zardaxt? Zardaxt (often found as zardaxt.py

distributions often leverage a standard window size of 29200 .

: The initial buffer size allocated for data stream processing varies widely by system architecture.

The scoring link accounts for the network distance (hops) to guess the true initial TTL based on the received TTL. 2. TCP Window Size

by comparing the TCP/IP fingerprint against the claimed "User-Agent" in the browser; a mismatch (e.g., a User-Agent claiming to be Windows but a TCP fingerprint scoring high for Linux) often flags the user as a bot or proxy user.

Unmasking Your Visitors: A Guide to Zardaxt OS Scoring Have you ever wondered if the "iPhone" visiting your site is actually a Linux-based bot? In the world of web security, things aren't always what they seem. Today, we’re diving into , a powerful tool for passive TCP/IP fingerprinting

The normalized signature is run against a database of known operating system configurations. The algorithm weighs parameters based on how much entropy (unique identification power) they bring to the table. 3. Scoring Distribution
